ICD-10 code for myelinolysis

The ICD-10-CM code for myelinolysis is G37.2 (Central pontine myelinolysis).

Within G37 (other demyelinating diseases of central nervous system), G37.2 is specifically for central pontine myelinolysis. Related codes cover diffuse sclerosis of central nervous system (G37.0), central demyelination of corpus callosum (G37.1), acute transverse myelitis in demyelinating disease of central nervous system (G37.3), subacute necrotizing myelitis of central nervous system (G37.4), Concentric sclerosis [Balo] of central nervous system (G37.5), other specified demyelinating diseases of central nervous system (G37.8) and demyelinating disease of central nervous system, unspecified (G37.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 058 (Multiple Sclerosis and Cerebellar Ataxia with MCC, relative weight 1.8438), DRG 059 (Multiple Sclerosis and Cerebellar Ataxia with CC, relative weight 1.2002) and DRG 060 (Multiple Sclerosis and Cerebellar Ataxia without CC/MCC, relative weight 0.9247), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
